Jquery中给animation加更多的运作效果实例

            var c = firstNum + diff;
            return c * ((p = p / 1 – 1) * p * p * p * p + 1) + firstNum;
        },
        quintEaseInOut: function (p, n, firstNum, diff) {
            var c = firstNum + diff;
            if ((p /= 0.5) < 1)
                return c / 2 * p * p * p * p * p + firstNum;
            else
                return c / 2 * ((p -= 2) * p * p * p * p + 2) + firstNum;
        },
        // *******  sine
        sineEaseIn: function (p, n, firstNum, diff) {
            var c = firstNum + diff;
            return -c * Math.cos(p * (Math.PI / 2)) + c + firstNum;
        },
        sineEaseOut: function (p, n, firstNum, diff) {
            var c = firstNum + diff;
            return c * Math.sin(p * (Math.PI / 2)) + firstNum;
        },
        sineEaseInOut: function (p, n, firstNum, diff) {
            var c = firstNum + diff;
            return -c / 2 * (Math.cos(Math.PI * p) – 1) + firstNum;
        }
    }
});

调用:

$(“#div”).animate({
    left: v
}, 1000, “circEaseOut”);
